Configuration

Module connections/LED

The connections of the module terminal are the following:

Description of the LED:

● Off: Module is not powered. Uext (24 V) is missing.

● On: Module is running without errors

● Blinking slow: Channel error (Over range/under range/short circuit/open load)

● Blinking fast: Uext is lower than specified (< 19 V)

How to configure the inputs

Each input channel is configured by a DIP-Switch with four switches. The function of

each switch is the following:

Switch nr. Off On

1

2

3

4

Differential Mode

Gain=1

Single Ended Mode

Current Shunt On

Supply for external Resistors On

Gain=0.25

According to this table, the configuration for the different modes of operation is as fol-

lows:

Voltage mode

0...10 V

Current mode

0...20 mA

4...20 mA

Temperature mode

Pt1000 (-50...400 ̊C)

Pt500 (-50...400 ̊C)

Ni1000 (-60...200 ̊C)

Resistor mode

0...2500 Ω

How to configure the outputs

Since the outputs are configured by software (with the corresponding FBox or FB),

there is no need to configure the mode of operation of the outputs with any kind of

jumpers or DIP-Switches.
